Description
Изобретение относитс к способу очистки -промышлен-ных углеводородных газов от окислов азота при использовании газов как сырь дл химических синтезов.The invention relates to a process for the purification of industrial hydrocarbon gases from nitrogen oxides using gases as a raw material for chemical syntheses.
Известен способ очистки коксового газа от следов окиси азота путем восстановлени и гидрировани .последних в присутствии сульфидов железа, никел , кобальта и меди при атмосферном давлении и температуре 70- 130°С.A known method of purifying coke oven gas from traces of nitric oxide by reducing and hydrogenating the latter in the presence of iron sulfides, nickel, cobalt and copper at atmospheric pressure and a temperature of 70-130 ° C.
Существенными недостатками этого типа катализаторов вл ютс необходимость расходовать редкие металлы, чувствительность к дам и сложность регенера:ц:к1и.Significant disadvantages of this type of catalysts are the need to expend rare metals, sensitivity to women and the complexity of the regenerator: n: k1i.
Дл удешевлени и упрощени процесса каталитической конверсии окисей азота ;нредлагаетс .процесс вести в присутствии золы эстонского горючего сланца-кукерсита, получающегос как многотоннажный промышленный отход энергетических м сланцеперерабатывающих предпри тий эстонского сланцевого бассейна.To reduce the cost and simplify the process of catalytic conversion of nitrogen oxides, it is not necessary to carry out the process in the presence of ash from Estonian combustible shale-kukersite, resulting in a large-scale industrial waste of energy shale enterprises of the Estonian shale basin.
Эффективность народнохоз йСтвениого использовани данного .катализатора определ етс его дешевизной, высокой избирательной способностью и полной нечувствительностью к типичным каталитическим дам: сернистым соединени м, окиск углерода и вод ному пару.The effectiveness of the national use of this catalyst is determined by its low cost, high selectivity and total insensitivity to typical catalytic women: sulfur compounds, carbon monoxide and water vapor.
новки по переработке эстонского горючего сланца с твердым теплоносителем (УТТ) на сланцехимическом комбинате в ЭССО. Испытани проведены в лабораторном масштабе На стационарном слое катализатора. Очистке подвергаетс углеводородный газ, вырабатываемый УТТ и содержащий 30-35 об. % моноолефипов С2-Cs, около 8 об. % окиси углерода , 100-150 сернистых соединений, насыщенный вод ными парами. Полученные при этом результаты показывают, что при температуре в реакционной зоне 350-500°С и скорости прохода газа через реактор около 200 окись азота, содерл аща в исходном газе в количестве до дес тка миллионных долей объема, конвертируетс практически полностью, тогда как конверси моноолефинов , целевых компонентов газа, пе превышает 3% их начального количества.New shale recycling of Estonian fuel with solid heat carrier (UTT) at a shale chemical plant in ESSO. Tests were carried out on a laboratory scale on a fixed bed of catalyst. The hydrocarbon gas produced by UTT and containing 30-35 vol. % of mono-olepses C2-Cs, about 8 vol. % carbon monoxide, 100-150 sulfur compounds, saturated with water vapor. The results obtained here show that at a temperature in the reaction zone of 350-500 ° C and a gas flow rate through the reactor about 200 nitric oxide, containing up to ten ppm in the initial gas, is converted almost completely, while the conversion of mono-olefins , target gas components, ne exceeds 3% of their initial amount.
При непрерывной работе в течение нескольких часов заметного падени активности катализатора не «аблюдаетс .With continuous operation over several hours, a noticeable drop in catalyst activity is not abluted.
П.редмет изобретени P. subject of the invention
Способ очистки промышленных углеводородных газов от окислов азота путем каталитической конверсии, отличающийс тем, что, с целью упрощени процесса, последний ведут при температуре 350-500°С в присутствии золы кукерсита.The method of purification of industrial hydrocarbon gases from nitrogen oxides by catalytic conversion, characterized in that, in order to simplify the process, the latter is carried out at a temperature of 350-500 ° C in the presence of kukersite ash.
